accented characters

Primary tabs

How do you allow accented chracters to flow through the engine without erroring out? I read something about adding a "!" in MSH-18 to accept the default coding, but now it gives me an error about "No translation table found".  Does Intersystem have anything out of the box to account for accented letters?  Does this need to be coded?


Hi Cedric,

It sounds like you are adjusting the messages to have ! in the MSH:18 field. Unless I'm misunderstanding, that seems like a misinterpretation of the DefCharEncoding documentation, which I will include here:

Default Char Encoding

Normally the encoding found in MSH:18 is used, but an "!" at the start of the DefCharEncoding setting will forcibly use whatever encoding you specify.

Hope that helps.

Yes, that's what I'm trying to do. But MSH:18 is blank. There isn't any fields after MSH:14. So I tried just adding the "!" to the field, and it error out.

DefCharEncoding is a setting for HL7 services that you would add the ! to in order to enforce a particular encoding. If MSH:18 is blank then whatever encoding is in DefCharEncoding will be used, whether or not you use ! for the setting. ! in the message in MSH:18 would probably trigger an error as ! doesn't represent a valid encoding.

Typically all strings are UTF encoded.
The average text often consist of  single-byte characters  (a subset of UTF-8)   
As soon as a multibyte character joins the string the whole string just uses WIDE characters

The conversion happens totally internal.
depending on your needs you can select the national language table.
different languages sort differently.   e.g German äöü vs. aou 

Hey Cedric

What characters are you trying to handle exactly? Just accented Es? Like é?

Good to see you on here!
